Elements and Performance Criteria

1. Prepare to determine operating conditions of air conditioning system
   • WHS/OHS hazards, risk control methods, relevant standards, codes and legislation are obtained and applied in accordance with workplace procedures
2. Safety hazards which have not previously been identified are assessed, reported and advice on risk control measures is sought from supervisor
3. System design operating conditions are obtained from documentation or supervisor to determine scope of work to be undertaken
4. Advice is sought from the supervisor to ensure work is coordinated effectively with others
5. Materials required for the work are identified and obtained in accordance with workplace procedures
6. Tools, equipment and testing devices needed to determine operating conditions are obtained and checked for correct operation and safety in accordance with workplace procedures
7. Determine operating conditions of air conditioning system
   • Measuring system operating parameters are implemented in accordance with job requirements and workplace safety procedures
8. Air conditioning system is checked and isolated in accordance with workplace procedures
9. Actual and specified range of operating conditions are determined from measured and calculated values as they apply to air conditioning system in accordance with workplace procedures
10. Methods for dealing with unplanned situations/events are discussed with appropriate person/s and documented
11. Unexpected situations are dealt with safely and with the approval of relevant person/s
12. Operating conditions for air conditioning system are determined without damage to apparatus, circuits, the surrounding environment or services using relevant workplace sustainable energy practices in accordance with workplace procedures
13. Complete work and report
    • Worksite and equipment are cleaned and made safe in accordance with workplace procedures
14. Operating conditions are documented, including identification of any parameter that is not within the specified range for the of air conditioning system, in accordance with workplace procedures
